/// The BITMAPINFOHEADER contains all the details about the video stream such
/// as the actual image dimensions and their pixel depth. A source filter may
/// also request that the sink take only a section of the video by providing a
/// clipping rectangle in rcSource. In the worst case where the sink filter
/// forgets to check this on connection it will simply render the whole thing
/// which isn't a disaster. Ideally a sink filter will check the rcSource and
/// if it doesn't support image extraction and the rectangle is not empty then
/// it will reject the connection. A filter should use SetRectEmpty to reset a
/// rectangle to all zeroes (and IsRectEmpty to later check the rectangle).
/// The rcTarget specifies the destination rectangle for the video, for most
/// source filters they will set this to all zeroes, a downstream filter may
/// request that the video be placed in a particular area of the buffers it
/// supplies in which case it will call QueryAccept with a non empty target
